# The 23-Skidoo Wind Tunnel: Physics, Folklore, and Navigating the Flatiron's Famous Drafts Located at the intersection of 23rd Street and Fifth Avenue, the Flatiron Building is one of New York City's most iconic landmarks. Its triangular wedge shape creates a unique meteorological phenomenon known as the 'wind tunnel' effect, where powerful downdrafts can be felt by visitors. In this guide, we will explore the aerodynamic physics behind this effect, delve into the historical origin of the phrase '23-Skidoo', and provide practical tips for navigating the gusty plaza. ## The Physics of the Wind Tunnel Effect The Flatiron Building's triangular shape creates a channeling effect, where the wind is funneled through the narrow space between the building and the surrounding streets. As the wind accelerates, its velocity increases, creating a region of low air pressure behind the building. This pressure difference creates a powerful downdraft, which can be felt by visitors on the plaza. ## The Origin of '23-Skidoo' The phrase '23-Skidoo' originated in the early 20th century, when police would disperse onlookers at the intersection of 23rd Street and Fifth Avenue. The term 'skidoo' was a colloquialism for 'hurry up', and '23-Skidoo' referred to the police's practice of quickly clearing the area. Today, the phrase is still used to describe the experience of being swept away by the powerful downdrafts at the Flatiron. ## Navigating the Gusty Plaza Visitors to the Flatiron Building should be prepared for the gusty conditions on the plaza. Here are some practical tips for navigating the wind: * Hold onto your hat and any loose items, as the wind can be strong. * Use a camera with a secure strap or consider using a windproof camera case. * Avoid using umbrellas, as they can be blown inside out. * Take photos quickly, as the wind can make it difficult to hold your camera steady. ## Conclusion The 23-Skidoo wind tunnel is a unique and fascinating phenomenon that has captivated visitors for over a century. By understanding the physics behind the wind tunnel effect and the historical origin of the phrase '23-Skidoo', we can appreciate the Flatiron Building's iconic status and navigate the gusty plaza with confidence.
